LIQUID SPRAYER.

Application filed tvccober 1, 1921. Serial No. 594,750.

To all whom it may co'iwem:

Be it known that I, MATHEW F. Burnsnonr, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Liquid Sprayers, of which the following is a specification.

This invention relates to a liquid sprayer and has for its object to provide a simple and durable construction in which the parts can be readily taken apart so as to clean the same and also to provide a construction which will allow the sprayer to be easily operated.

' connected to the same.

Fig. 2 is an enlarged longitudinal vertical section of the sprayer.

Fig. 3 is an enlarged detailed fragmentary section of the needle valve and cap.

My improved sprayer, in a preferred embodiment, comprises substantially a straight tubular body 1 having a plug 2 mounted within the tube 1; and packing rings 3 are preferabl mounted in grooves formed in the perip cry of the plug so as to prevent leaking between the plug and the tube. In this embodiment, a straight sleeve 4: projects forwardly from the plug 2 and is in axial alinement with a central bore 5 in the plug 2. Adjustably screw threaded on the for ward end of the member 1 is a nozzle cap 6 delimiting a chamber and having a central opening 7 extending forwardly from an en'- larged recess 8. A valve seat is formed in the opening 7 in the cap by placing a disk 9 of relatively softer material therein and a nut 10 shown as provided with an aperture of substantially the same diameter as the opening 7 and as having threaded engagement with the cap is adapted to hold the disk 9 in position. A tapered aperture is formed in the disk and is adapted to be closed by the needle valve .11 which projects rearwardly through the bore 5, a packing gland 12,. and slidably journaled in a bearing member 13 suitably held in a tubular member 14: extending rearwardly from the member 1 and suitably fastened thereto as by rivets 15, members 1 and 14, together with the plug 2, having a common axis, and constituting the body of the nozzle.

The means for actuating the valve stem, comprises in the present embodiment, substantially a lever 16 pivotally connected as at 17 to a link 18 which is pivotally connected as at 19 to the tubular member 14: and projecting downwardly from the lever 16 is an actuating handle 20. A spring 21 surrounds the valve stem and abuts the bearing member 13 at one end and a cup 22 at its other end, which cup has engagement with the stem as by a pin 23 positioned on the rearward side of the same and has engagement with the lever 16 as by a curved surface 24 formed on the opposite side of the cup and a vertical slot 25 is formed in the lever so as to allow the rod to pass through the same and it is thus seen that when the handle is pushed forwardly the valve stem will be pulled back out of engagement with the aperture of the disk, 9, the needle 11 being shown as extending straight through the nozzle to project therefrom at either end, although engaged within said nozzle by actuating means.

Projecting downwardly'from the member 1 is a short annular extension upon which is screw threaded a downwardly projecting hollow handle 26. Positioned with in the handle shown as extending substantially at right angles to the body of the nozzle are water and air conduit tubes 27 and 28. Screw threaded into the lower portion of the plug 2 and communicating with the axial bore 5 is a conduit 29 leading from the water conduit 27. An air conduit 30 communicates with the conduit 28 at one end and terminates in the annular space formed around the sleeve 4..

Connected to the conduits 27 and 28 are hose 31 and 32 connected respectively to a water supply pipe 33 and an air supply pipe 34 which has any suitable valve controlling means 35 positioned therein and the pipe 33 communicates with a liquid reservoir 36 which has a drain pipe 37 and an inlet pipe 38, the inlet from the latter being suitably controlled by any ordinary float construction as shown at 39. The air pipe 3 1 communicates with the upper portion of the reservoir as by a pipe 40.

Thus in the operation, air pressure from any suitable source (not shown), is forced into the reservoir which causes the liquid to be forced out through the pipe 33, hose 31,

' up through the conduit 27 out. through the 28 and into the annular space or chamber surrounding the sleeve and out through the aperture in the disk 9, which will cause the liquid to be sprayed which also passes through the aperture.

Various changes may be made in thenctails of construction, without departing from the spirit of my invention as set forth in the appended claims.

\Vhat is claimed is:

1. A liquid sprayer comprising a tubular member to which is secured a hollow handle, a plug in the said tubular member having liquid and air conduitS,a nozzle cap adjustably mounted on the forward end of said tubular member, a valve stem slidably mounted in said plug and adapted to close said nozzle, air and liquid pipes extending through said hollow handle and having communication with said conduits, said pipes being supported .by said plug, and means for actuating said valve stem. 2. A liquid sprayer comprising a tubular member, air and liquid conduits in said member terminating in a common'chamber, a nozzle cap having an aperture leading from said. chamber, an apertured disc of softer material in said aperture, a nut for securing said disc, a needle valve for controlling the flow through said nozzle cap, the needle of said valve being seated on said disc and adapted to project through said disc in said nozzle cap, and means for actuating said valve.

3. A liquid sprayer comprising a tubular member, a plug having an axial opening mounted in said member, a sleeve projecting forwardly from said plug and having a co-axial opening, a nozzle cap mounted on the forward end of said tubular member, a valve stem slidably mounted in said plug and adanted to close anoutlet extending through said nozzle cap only, said stem projecting rearwardly through both said plug and a, tubular extension, valve actuating mechanism mounted on said' tubular extension, and air and liquid conduits communicatin with the interior of said plug.

4.5; sprayer comprising a longitudinal body member, a nozzle cap-carried on one end of said member and delimiting a chamber, a handle projectin downwardly substantially at right angfiss from said body member, air and liquid conduits positioned within said handle and communicating with said chamber, a spring seated valve vided with a stem longitudinally shiftable through said body member, disc of soft material secured as a valve seat in said nozzle cap, said stem being adapted to close said nozzle cap by contact with said disc, and means for actuating said stem.

' 5. A sprayer comprising a tubular body, a plug positioned therein and provided with conduits, a nozzle cap secured on one end of said tubular body and provided with an pro- 1 aperture, a valve seated in said aperture,

a tubular extension secured to the other end of said tubular body, valve actuating means secured to said tubular extension, a handle In testimony whereof I have signed my name to this specification.
